,BRICK-PROTECTOR.

SPEQIFICATION forming part of Letters Patent No. 502,987, dated August8, 1893.

Application iiled January 28, 1893. Serial No. 460,104. (No model.)

To all whom it may concern-3 Be it known that LNLS OLSON, of Superior,in the county of Douglas and State of Wisconsin, have inventedV a newand Improved Brick-Protector, of which the following is a full, clear,and exact description.

My invention relates to improvements in brick protectors of the kinddescribed in Letters Patent of the United States No. 432,430, dated July15, 1890; and the objectof my invention is to improve the constructionshown in said patent and provide sheds or protectors' with folding wingsor roofs; to arrange gutters so that the water shed by the wings orroofs will be carried away to provide means for covering the alleysbetween groups of pro-v tectors; to provide stops which will prevent thewings from being raised too high and consequently broken, and to providemeans for raising theseveral wings eitherseparately or simultaneously,as described; to the end that the yard may be always kept dry and workproceededvwith even though it may rain.

My invention consists in certain features of construction andcombinations of parts, as will be hereinafter described and claimed.

Reference isto be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a broken central longitudinal section of a system ofprotectors embodying my invention. Fig. 2 is avertical section on theline 2--2 in Fig. 1,showing in section, the

roof for covering an alley between two grou ps v of protectors, andshowing the protectors proper in end elevation. Fig. 3 is a crossSection on the line 3-3 in Fig. 1.' Fig. tisa detail cross section,showing. the manner in which the hoisting rope is secured; and showingalso in detail the manner in which the wings or roofsare pivoted. Fig. 5is a detail sectional view of a 4portion of the hoisting mechanism andthe hangers which limit the upward movement of the sheave blocks andwings; and Fig. 6 is a detail sectional plan of the hoisting mechanismon the line 6;-6 in Fig. 1.

The protectors illustrated in the drawings have the same generalcharacteristics as those Shown in my former patent alluded to, eachprotector comprising base plates 10, vertical posts 1l erected on thebase plates and provided with braces l2, and oppositely swinging arms 13pivoted near the tops of the posts and adapted to swing vertically',wings 14 secured to the arms and formed of overlapping boards, the cap15 to'cover the joint between the opposing wings, and the inwardly anddownwardly extending links 16, which connect opposite arms 13 and whichare pivotally connected together at their lower ends and are alsopivoted to the sliding sheaves as hereinafter described.

The above construction is substantially like that shown in my formerpatent and is notv claimed as a part of this invention.

The wings`14 have at Vtheirlower and outer edges, gutters 17, which arecarried by the arms 13 and which receive and carry off the water whichiows from the wings. To guard against any leakage between the adjacentand parallel protectors, the gutters 17-which come together, as shown inFig. 3, are covered kby anv inverted gutter or shield 13 whichis'supp'orted by hangers 19, they latter being carried by cross braces2O extending from one cap 15 to the opposite one." Extendinglongitudinally through each shed; that is, be`

neath each cap 15, is a brace or reach pole 21 to which at intervals aresecured depending hangers 22, and the hoisting-rope of each protectorextends longitudinally through slots in the posts 1l and over guidepulleys 2i in said slots, and also 'between the hangers 22.

The hoisting rope 23 extends over guide pulleys 25in the hangers'22,thence downward around sheave pulleys 26 in the sheave blocks 27, andthe ropes are then extended upward and secured, as shown at 2S, to thehangers.

There is avropeffor each sheave block 27 and, as the sheave blocks arepivotally connected with the links 16 of the swinging wings, it will beseen that when the ropes 23 are pulled in one direction, the'Y sheaveblocks will beV raised and the wings also raised,while if the ropes arepulled in the opposite direction the blocks and wings will be lowered.The ropes 23 are at one end made fast to a pulley block 29, which isarranged near one of the ends posts 11, aud extending around the pulleyin this block is a rope 30 which extends outward and downward over apul- IOO ley 31 in the post, and is made fast toa crank windlass 3lawhich is provided with a suitable pawl 32 and ratchet wheel 32 toprevent it from turning in the wrong direction. Any suitable Windlassmay, however, be used for operating the rope. The opposite member of therope 30 passes outward and downward over a pulley 33 in the post, andthence downward beneath the base plate 10 and is secured to a cable 34held to move in a guide or conduit 34 which extends at right angles tothe protector. The rope 30 of each protector or shed is connected withthe rope 34 and with the windlass in the manner specified and asillustrated in Figs. 1 and 2, and the cable 34 is adapted to be operatedby a suitable engine. It will be seen then that if one pairof wings 14is to be raised, it may be done by simply turning the windlass 31, asthe winding of the rope 30 on said windlass pulls the block 29 towardthe end post 11 and the ropes 23 are thus pulled so as to lift thesheave blocks 27, the links 16, and the wings 14. If, however, a wholeseries of wings are to be raised, the rope or cable 34 is wound by theengine so that the ropes 30 are simultaneously pulled and all the wingsraised in the manner described.

lVhen the `wings are to be collapsed, the pawls 32 are released and theropes 23 pulled in the opposite direction by means of ropes 35 which aresecured to the ropes 23 and which extend outward through slots 35a inthe post 11, at one end of the shed or protector, although as a generalthing the wings will drop of their own weight.

It is customary in a brick yard to arrange the protectors or sheds ingroups or series, and in Fig. 1 I have shown two such groups, the alleybetween which is covered by the roof 36 which is supported upon aframework consisting of rafters 3G and cross timbers 36h, the crosstimbers being supported on the caps l5 of the opposite protectors.

From the foregoing description it will be readily seen that any one ofsaid protectors may be operated to either raise or lower the wings, thatifA desired the entire series may be simultaneously operated, and thatthe whole yard may be completely covered and the water carried away sothat the bricks beneath the protectors are kept from injury.

It will be seen that the water, which is discharged by the roof 36, iscaught by the adjacent wings 14 and by them discharged into the gutters.It will be further observed that when either pair of wings is raised orall are simultaneously raised, the sheave blocks 27 will rise and theirupward movements will be limited by the hangers 22 against which thesheave blocks strike, so that the upward movement of the wings is thuslimited and the apparatus is prevented from being broken.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination with the protector sup ports, theswinging wings pivoted on the supports, and the vertically movablesheaves pivotally connected with the wings,.of stops or hangers arrangedto limit the upward movements of the sheave blocks and consequently ofthe wings, substantially as described.

2. In a brick protector, the combination with the series of protectorsor sheds, each protector comprising supporting posts, oppositelyarranged and vertically swinging wings, vertically movable sheaveblocks, and links pivoted to the sheave blocks and to the wings, ofhorizontally movable pulley blocks arranged near the ends of theprotectors, hoisting ropes connecting the pulley blocks .with the sheaveblocks so as to operate the same, awindlass arranged at each protector,awinding cable extending adjacent to the protectors, and operating ropessecured to each wind lass and to the cable extending around the pulleysof the pulley blocks, substantially as described.

3. The combination with the parallel protectors having verticallyswinging wings, of gutters secured to the free edges of adjacent wings,and a shield supported over the adjacent edges ot` the gutters,substantially as described.

4. The combination with the series of protectors comprising verticalposts and wings pivoted thereon, said protectors being arranged ingroups, so as to leave an alley between each two groups of a removableroof extending from one group of lprotectors to the other over the saidalley and arranged ,to discharge upon the protector wings, substantiallyas described.
